If you would like more information on a particular geologic time period,
you can scan a complete listing of our exhibits by clicking on the
Web Lift below. You can also use the lift on any of our pages to
look up a particular taxon (group of organisms), or to look up an unfamiliar
word. If you would like more information about getting around within the
exhibits, we now have a page on navigating,
which contains hints and help.
